Definition

Ovine pulmonary adenocarcinoma (OPA), also known as ovine pulmonary adenomatosis and jaagsiekte, is a contagious tumour of sheep and, rarely, of goats. It is a progressive respiratory
disease, principally affecting adult animals. The disease occurs in many regions of the world. A betaretrovirus (jaagsiekte sheep retrovirus: JSRV), distinct from the non-oncogenic ovine
lentiviruses, has been shown to cause the disease.
